A1 Gheeraert, Etienne A1 Araújo Gay, Daniel A1 Pernot, Julien A2 Ciencia de los Materiales e Ingeniería Metalúrgica y Química Inorgánica AB In this letter, we report on the improvement of gate controlled Al2O3/(100) boron doped (B-doped) oxygen-terminated diamond (O-diamond) Metal Oxide Semiconductor Capacitors using 40 nm thick Al2O3 deposited by Atomic Layer Deposition at 380 °C and then annealed at 500 °C in vacuum conditions. The high quality of Al2O3 and an Al2O3/diamond interface is verified thanks to electrical measurements and Transmission Electron Microscopy (TEM) measurements. A density of interface states lower than 1012 eV-1 cm-2 is measured from the flat-band regime to the depletion regime. The shift of the flat-band voltage and the leakage current through the oxide are significantly reduced in good agreement with the mono-crystalline character of the Al2O3 layer revealed by TEM PB AIP Publishing SN 00036951 YR 2018 FD 2018 LK http://hdl.handle.net/10498/31011 UL http://hdl.handle.net/10498/31011 LA eng DS Repositorio Institucional de la Universidad de Cádiz RD 22-sep-2026
